CORN-HARVESTERI $PECIFICA'IION formingpart of Letters Patent No. 677,927, dated July 9, 1901".

Application filed October 3,1900. Serial No. 31,847. (No model.)

To all whom, it may concern.-

Be it known that 1, DAVID BINNs, a citizen of the United States, residing at Oampchase, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Corn-Harvesters, of which the following is a specification.

My invention relates to the improvement of corn-harvesters; and the objects of my invention are to provide a corn-harvester with improved mechanism for carrying the stalks rearward from the cutters and for delivering the shock from the carrying mechanism, to provide improved means for properly feeding the stalks onto the traveling carrying-aprons, and produce other improvements, the details of construction and operation of which will be more fully pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanying drawings, in which Figure 1 is a plan view of my improved ma-' chine. Fig. 2 is a plan view with a portion of the parts in the upper portion of the machine, together with the shocking-frame, removed for the purpose of illustrating the gearing and parts connected with the machinebase. Fig. 3 is a transverse section on line as so of Fig. 1. Fig. 4 is a detail plan view of one of the endless stalk-feeding chains which is employed in the upper portion of the machine. Fig. 5 is a detail view in elevation, illustrating the gear connection whereby motion is transmitted from the main shaft of the machine to the feeding-chains. Fig. 6 is a detail View in perspective of a portion of one of the feeding-chains. Fig. 7 is a central vertical section of one of the main shaft-;

driving sprocket-wheels and its ratchet con: nection with said shaft. Fig. Sis a sectional View on line y y of Fig. 7. Fig. 9 is a side elevation of the machine; and Fig. 10 is a detail view in elevation of one of the ground- Wheels, showing a portion of its axle.

Similar numerals refer to similar parts throughout the several views.

In carrying out my invention I employ a suitable framework, which comprises parallel side frame-bars 1, longitudinal and parallel frame-bars 2, arranged on opposite sides of the center of the width of the machine and extending throughout the length thereof, and

cross frame-bars 3. 7 From the side frame-bars 1 rise frame-standards 4, which are connected at their upper ends by top framebars 5. From the upper sides and forward portions of the parallel top side frame bars 5 extend forwardly and downwardly guide boards 6. Suitably supported from f rame-standards ris ing from the base-frame on the inner side of each of the guide-boards 6 is an inner guideboard 7, each pair of these guide-boards 6 and 7 having their forward and tapering end portions formed flaring and having their upper and rear end portions diverging, as indicated more clearly in Fig. 1 of the drawings.

8 represents a transverse axle which is secured in the base-frame side bars 1 at opposite points in the rear portion of the machine, said axle having its end portions bent upward, as indicated more clearly in Fig. 10, and having journaled on outwardly-project ing spindle portions thereof ground-wheels 9. Each of the ground-wheels carries on its outer side a smaller sprocket-wheel 10, over each of which passes a chain belt 11, these chain belts extending forwardly and running over comparatively small sprocket-Wheels 12, carried on the outer end portions of a transverse shaft 13, which is j ournaled in the base-frame. The shaft 13 carries on the outer side of each of the frame-bars 1 abevel gear-Wheel 14, and ad jacent to the inner frame-bars 2 carries similar bevel gear-wheels 15. Each of the sprocketwheels 1 2 is constructed so as to run loose on the shaft 13 when a backward motion is imparted to the ground-wheels. In accomplishing this object I may employ any well-known form of ratchet connection between the shaft and sprocket-wheel, but preferably employ the construction which I have more clearly illustrated in Figs. 7 and 8 of the drawings. In this construction the sprocket wheel 12 is provided with an inward hub-like extension 12 in the periphery of which are formed sockets 12". Into each of these sockets is inserted a spring 16, upon which bears the inner end of a pawl-bolt 17. Surrounding the hub extension 12 of the sprocket-wheel is a cup-shaped body 18, the central hub portion of which is fixed on the shaft 13. The inner wall of the cup 18 is, as indicated more clearly in Fig. 8 of the drawings, formed with cam recesses 19, each of which is in the nature of a notch formed by the junction, of a straight shoulder 20 and a tangential curve 21. It is obvious that the spring-actuated pawl-bolts 17 will follow said tangential curves during the rear or backward motion of the groundwheel, but will remain in engagement with the shoulder portions 20 of said recesses 19 when the machine is moving forward thus IO insuring a rotation of the shaft 13 with the sprocket-wheel. Suitably journaled in the framework of the machine are upwardly-extending and forwardly-inclined outer side shafts 22, the lower end of eachof said shafts 15 carrying a bevel gear-wheel 23, which gear withthe bevel gear-wheelspli. (See Fig. 5.)

. 24-represents1shaftswhich are parallelwith the shafts 22 and which are similarly jour- -naled,in the framework ofthe machine, the zo-lowenend portionsof said shafts carrying bevel gear-wheels 25, which gear with the .wheels 15. Upon the shafts 22 and 24 are ;.car1:iecl, at points above the gear-wheels 23 .and 25, sprocket-wheels, which are indicated 25 at 26 and 26; Upon the upper endportion ofeach of;the shafts 22 is carried a sprocketwheel 27, the latter being supported at a point i immediately below the outer guide-boards 6. Similar sprocket-wheels arecarried at oppo- 30. site points on the shafts 2%. Running over the sprocket-wheel 26 is a chain belt 28, which running forward passes over a sprocket-wheel 29, mounted on the corresponding base-frame ,bar 1, the chains 28 being thus inclined, as shown. 1 In a similar manner each of the sprocket-.- wheels 26 is rconnected with, a ;sprocket-- wheel corresponding with the sprocket-wheel 29 on the inner side of and iopposite the latter through the medium. of a chain belt 30. These chain belts 28 and 30 .are provided at intervals with outwardly-projecting carrying-fingers 31. Running over each of. the sprocket-wheels 27 is the inner end of a chain carrier-belt 32, these belts run- 45..ning forward beneath the side boards 6 and over, sprocket-wheels 33, which are journaled ,in the lower and forward end portion of the framework. The outer line ofeach of the chains 32 also runs over a guidesprocket- 5o avheel 34, the latterbeing journaled beneath theiinner portions of the side boards 6. ,As

. indicated in the drawings, each of the chains 32 carries at intervals outwardly-projecting .-fingers 35. These chains 32 are so arranged beneath theguide-boards 6 as to cause their fingers 35 to project, as shown in Fig. 1 of the drawings,v beyond the inner edge portions of said guide-boards. Running beneath theinner guide-boards 7 are similar chain belts 37, 6o. thefingers 38 of the latter projecting toward the fingers 35 of the chains 32. These inner The chains 32 and 37 may, if desired, as indicated in Fig. 6 of the drawings, bearranged torun within channeled guide-bars 32.

Rising from the parallel frame-bars 2 in the rear portion of the machine are the converging walls of a partition-frame 39, which serve to support the shocks. Journaled transcarried upon the shaft 41 between the framebars 2 and 1 on each side of the partitionframe. These SPX'OOkBiHWhGGlS l2 and 43 are connected by horizontal and parallel closelyarranged chain belts 44in Upon the shaft .13, between the frame-bars 2, I mount loosely a sprocket-wheel 45, which througluthdmedium of a crossed chain belt 46 connects said sprocket 4:5 with a rear sprocket-wheel 47 on the shaft 4:0. The sprocket-wheel 45 ispro vided, as indicated at 48, with a toothed clutch+hub projection, with the teeth ofswhich are adaptedto be engaged the teeth of one end, of a clutch-body ett), which is ikeyed to slide on the shaft .13; I also I. mount loosely on the shaft 13 a. gear-wheel. 50, one. side of which is provided with a toothed clutch-hub 51, the teeth of which areadapted to be engaged with the teeth of the sliding clutchbody 4L9. This clutch-body 4-9 haspivotally connected therewith the rear end of afornaled between the frame-bars2 in rear of the shaft 13, is mounted, a sprocket-wheel 54, which through the medium of a chain belt 55, which extends rearwardly therefrom, is connected with a sprocket-wheel 56, carried. on the shaft 40. The shaft 53 also carries a gearwheel 57, the teeth of which mesh With those of the gear-wheel 50, said wheel 57 being of greater diameter than the wheel 50.

In front of each set of carrying-ch ains-zlel: I provide a cutting device, wliiclnasshown in the drawings, has a forwardly-projecting cutting-blade 58, having its forward sharpened edge inclined inwardly, as shown. It is obvious, however, that any well'known form of corn-cutting device might be employed in lieu of the blades 58. The forward end portions of the frame-bars 2 have mounted therein a comparatively small ground-wheel59, beyond which said frame-bars are united and adapted to have connected therewith singletrees or other means of hitching one or more horses to the machine.

iAbove one of the upper frame-bars 5 is adapted to be journaled a ball or reel of suitable cord or twine, such as is indicated at 60. From this ball the cord runs rearwardly,

thence inwardly and transversely across the rear portion of the machine, passing between two sets of binding and guide rollers 61 and 62. Each of the rollers 61 is pivoted upon a pin rising from the upper side of the framebar 5, while each of the rollers 62 is provided with a short forwardly-extending arm 63, which is pivoted at 64 to said frame-bar. These rollers 61 and 62 are pivoted out of alinement with each other, so that a pull on the cord 60 toward that side of the machine on which the cord-ball is located will result in drawing said rollers into closer proximity to each other and in a binding of the cord between them.

It is obvious that my improved corn-cutting machine is designed to receive and out two rows of corn at a time, one row of stalks passing between the guide-boards 6 and 7 of each pair. Motion is contributed to the moving parts of the machine as follows: The forward rotation of the ground-wheels 9 results through the connection of the sprocket-wheels 12 and 10 in the rotation of the shaft 13. Assuming that the clutch 49 is in engagement with the clutch-hub 51 of the gear-wheel 50, it is obvious that comparatively slow motion will be contributed to the shaft lO through the gearing of the wheels 50 and 57 and the connection of the wheels 5i and 56. This slow motion of the shaft 40 is contributed to the chains 44, causing the upper lines of the latter to run rearward. Through the engagement of the bevel gear-wheels 14 and 15 with the wheels 23 and 25 motion is contributed to the shafts 22 and 24s, the chain belts 28 and 30, and 32 and 37. Through the inward traveling movement thus imparted to the fingers 35 and 38 the cornstalks are fed in upright positions between the guide-boards 6 and 7, and being out by the knives 58 said stalks are carried onto the rearwardly-moving aprons formed by the chains as. to carry the stalks rearwardly until a sufficient quantity thereof is crowded against the transverse rope or tie-cord 60 on each side of the partition-frame 39 to form a shock. The machine is now stopped and a sufficient amount of the cord 60 drawn between the clamping-rollers 61 and 62 to bind or tie the stalksintoshocks. Thisbeingaccomplished, the cord 60 is disengaged from those rollers 61 and 62 which are on the opposite side of the machine from that carrying the cord-bail, and the lever 52 is moved laterally until the teeth of the clutch 49 are in engagement with the teeth of the clutch-hub 48 of the sprocket- Wheel 45. By again starting the machine a comparatively rapid motion is nowimparted through the sprocket-chain 46 to the shaft 40, resultingin moving the shocks from the chain aprons off onto the ground. This being ac- These chain aprons serve complished, the lever 52 is again moved until the clutch 49 is in engagement with the clutchhub of the gear-wheel 50, thus again imparting a slow motion to the chain aprons and permitting sufficient quantities of the cut stalks to be again carried to positions for shocking.

From the above description it will be seen that a simple construction of cornstalk-carrying aprons is provided and that desirable means are employed in conjunction therewith whereby the shocks may be readily removed from said aprons.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a corn-harvester,the combination with a horizontal frame, of endless carriers-arranged to travel over said horizontal frame on opposite sides of the center of the width thereof, said carriers being arranged on horizontal shafts, a flaring or inverted-V-shaped partition arranged longitudinally on said frame between said carriers, a cutting device for each of said carriers and mechanism arranged between the carriers for driving the latter either at a fast or slow rate of speed, substantially as specified.
